Electronic cigarette and use method

Abstract

The invention discloses an electronic cigarette and a use method. The electronic cigarette comprises an atomizer, a heating element, a power supply, a control unit, and a capacitive transducer. The atomizer comprises an oil storage cavity used to store cigarette oil. The heating element is arranged in the oil storage cavity. The power supply is used to supply power. One end of the control unit is electrically connected with the power supply, and the other end is electrically connected with the heating element. The capacitive transducer is electrically connected with the control unit. The electrode of the capacitive transducer is arranged in the oil storage cavity, and is used to detect cigarette oil quantity in the oil storage cavity. The capacitive transducer is used to detect the cigarette oil quantity in the oil storage cavity, and cigarette oil quantity in the oil storage cavity can be accurately determined, so as to effectively solve a problem of dry heating of the heating element when the electronic cigarette does not have cigarette oil or cigarette oil quantity is not sufficient.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to an electronic cigarette and a use method. Background technique [0002] Electronic cigarettes, also known as virtual cigarettes, are a substitute for cigarettes. They are more and more popular among smokers because of their low harm to the human body, no second-hand smoke, no open flames, and no fire hazards. Electronic cigarettes on the market usually include an atomizer and a power supply component. The atomizer includes an atomization component, a heating element, and an oil storage chamber for storing e-liquid. The heating element heats the e-liquid to make the e-liquid mist Smoke is produced by melting, and the smoke flows out through the airflow channel to achieve the effect of imitating real smoke. [0003] The inventors of the present application have discovered during long-term research and development that when the e-liquid in the oil storage cavity is us...
